Subject: perf lock: Move common lock contention code to new file

Avoid references from util code to builtin-lock that require python
stubs. Move the functions and related variables to
util/lock-contention.c. Add max_stack_depth parameter to
match_callstack_filter to avoid sharing a global variable.
